Richard,

Funny thing, how RDRAM's work in so many other applications, except for Intel's i820 chipset? Any ideas?

The consensus opinion I can garner is that the problem is in the printed circuit board design/layout on the mobos. If it's fixable, as we heard (sort of, call it hinted or where's the announcement?) by reducing from 3 RIMMs down to 2, this implies traces and/or stubs too long or otherwise ugly. It doesn't imply the chipset. Still, Intel is holding back Camino, aren't they.

I'll bet the other applications in which Rambus works are much simpler in terms of PCB layout. Clear as mud still, isn't it?

Tony

Actually, it does work on the 820. Based on what I read, it is SOME of the motherboards. Circuit boards designed for such high frequencies often have problems.

However, people sell and then think and read.

Could it possibly be that Intel somehow screwed up the digital logic in Camino? Like for example only having the first time domain working reliably?

That would explain why the third slot would not work, even if the signal integrity on the bus is good. I believe the signal integrity must be good, by design. Rambus are too smart and too careful to get this wrong, and they educated the OEMs very well about how to design the motherboards right.
